Sockets Library Functions                      byteorder(3SOCKET)



NAME
     byteorder, htonl, htonll, htons, ntohl, ntohll, ntohs - con-
     vert values between host and network byte order

SYNOPSIS
     cc [ flag... ] file... -lsocket  -lnsl  [ library... ]
     #include 
     #include 
     #include 

     uint32t htonl(uint32t hostlong);


     uint64t htonll(uint64t hostlonglong);


     uint16t htons(uint16t hostshort);


     uint32t ntohl(uint32t netlong);


     uint64t ntonll(uint64t hostlonglong);


     uint16t ntohs(uint16t netshort);


DESCRIPTION
     These functions convert 16-bit, 32-bit, and  64-bit  quanti-
     ties between network byte order and host byte order. On some
     architectures these routines are defined as NUL  macros  in
     the include file . On other architectures, the
     routines are functional when the host  byte  order  is  dif-
     ferent from network byte order.


     These functions are most  often  used  in  conjunction  with
     Internet addresses and ports as returned by gethostent() and
     getservent().       See       gethostbyname(3NSL)        and
     getservbyname(3SOCKET).
